DELAVAN MANNING, OF MIDDLETOWN, NEW YORK.

Specification forming part of Letters Patent No. 18 [,192, dated August15, 1876; application filed 7 August 6, 1875.

To all whom it may concern:

Be it known that I, DELAVAN MANNING, of Middletown, in the county ofOrange and the State of New York, have invented certain mm and z z ofFig. 1.

Letters of like name and kind refer to like parts in each of thefigures.

The design of myinvention is to furnish a simple and efficient means forconnecting a pitman to or with a cutter-bar, and enabling all lostmotion occasioned by wearof the parts to be compensated for; to whichend it consists in the peculiar construction andcombination of parts,substantially as and for the purpose hereinafter specified.

In the annexed drawing, A represents a podestal formed upon or attachedto a cutter-bar, B, and provided with a cap, 0, that is held in place bymeans of two screws, D and D, one of which passes vertically througheach end of said cap, and has its lower threaded end contained within acorrespondingly-threaded opening, that is provided in the contiguousportion of said pedestal. Within the pedestal A are fitted twohalf-boxes, E and E, which are provided at their sides with the usualflanges e and e that bear upon the sides ofsaid pedestal and its cap 0,and insure the lateral position of parts. Said boxes closely fill thespace vertically, so that when said cap is screwed downward to place itshall bear upon and confine the former, while lengthwise of saidpedestal said boxes have less dimensions than the space within saidpedestal, and inv such direction are confined in position by means ofastscrew, '13, which passes inward through one of the jaws of the latter,and bears against the side edge of one of said boxes. A jamb-nut, f,placed upon said setscrew, outside of said. pedestal, enables the formerto be locked in place when adjusted thereto.

At the radial center of the boxes E and E is provided a round opening,6, one half of which is in each box, and within said opening is fitted'acorrespondingly-shaped sleeve, G, which just fills the same from end toend, and at its axial center is provided with a square longitudinalopening, g. The end of the pitman H is provided with an arm, h, which isturned horizontally to a position having a right angle to the line ofsaid pitman, and corresponds to and closely fills the opening 9 of thesleeve Gr, when it is secured in place by means of a screw, I, thatpasses into its end.

The operation of the device is as follows: The sleeve Gr operates as abushing for the arm or pin h of the connecting-rod, and receives allwear that would otherwise be thrown upon the latter, and can at anytime, and with but little expense and trouble, he removed and replacedby a new bushing. All wear of either bushing or boxes can be compensatedfor by screwing inward the set-screw, so that all annoyance and injuryfrom lost motion will be avoided, and the durability of parts largelyincreased.

Having thus fully set forth the nature and merits of my invention, whatI claim as new 1s The pedestal A, cap 0, boxes E and E, screws D, F, andI, sleeve Gr, having the central opening g, and pitman H, provided withthe pin. or arm h, said parts being constructed and combined with eachother, and with the cutter-bar of a harvester or mower, in the mannerand for the purpose substantially as specified.

In testimony whereof I have hereunto set my hand this 2d day of August,1875.
